The effect to the user is the same, the Dawn device gets lost. However
we need to make the difference internally because when the backend
device is lost we can clean up immediately. On the contrary on internal
errors, the backend device is still alive and processing commands so we
need to gracefully shut it down.

DeviceLost is a better name because we don't have a "context" as in
OpenGL.

This uses the OpenGL debug ouput functionality to make the driver call
us back when an error happens so we can ASSERT and fail.

This completely removes the dependency on glad by generating the GL
headers from gl.xml directly.
This requires adding khrplatform.h so all Khronos dependencies are
gathered in third_party/khronos.
Also removes a stray CMakeLists.txt that was still hanging out.

This makes the OpenGL entry points loaded at Adapter creation from the
getProcAddress passed in the DiscoveryOptions and update all GL calls in
the backend to go through the new OpenGLFunctions object.
A code generator is added that generates the function loader and list of
GL procs from Khronos' gl.xml file but we can't get rid of glad yet
because it is used to have the PROC typedefs and enum values.
